your kids eat so much different food, that's incredible!
2 of my 3 older kids are so extremely picky....I don't know why....but it makes it so difficult.
Thanks for your ideas, but I know 2 children who would not touch some of it *sigh*

my girls love pie dough put into tiny muffin molds with a little bit of meat in there (like a small meat pie, I also make them double crusted in regular muffin tins
mini meatloaves in muffin tins (you could put a tiny mozzerella ball inside of each to them
mini quiches
tortillas with herb cream cheese turkey and cheese and rolled up and cut like sushi rolls

I hope that helps a little
